Martial artists use board breaking as a method to demonstrate various attributes such as proper technique, power, targeting and speed among others. Board breaking is used in rank advancement testing, competitions, and even setting Guinness™ world records. Breaking boards requires one or more fellow students to hold the board (referred to as “holders”) for the student performing the technique (referred to as a “breaker”). While hand techniques are usually very accurate, foot techniques used in board breaking are usually not very accurate. High speed breaking techniques, particularly kicks, can cause noticeable injury to the hands and fingers of the holder(s) due to poor targeting by the breaker. Once struck/injured, a holder is likely to “flinch” or move the board/target on subsequent attempts, increasing the difficulty of successfully breaking the board/target.
Prior art attempts at providing some hand protection have been generally unsuccessful, for example, benefitting only the holder, or compromising between benefitting the breaker and benefitting the holder to the point that neither attempt at protection has worked. A prior art attempt at providing hand protection is illustrated by the sheath (12) in U.S. Pat. No. 4,807,302 by Cannella. A prior art product very similar to the disclosure of Cannella, and marked in the past with the Cannella patent number, has been and is commercially available, but it does not include the spikes 14 shown in the Cannella drawings. Other prior art attempts at hand protection include the holder(s) wearing of padded gloves.
Increased Chance of Injury:
The inventors believe, in order to avoid or minimize the chance of injury, a holder should hold a board/target with the hand and fingers generally in the position shown by the bare-hand portrayal in
These preferred hand and forearm positions may be described as the hand/wrist being rotated into the position in
The preferred position results in an angle between the main portion of the hand (and/or the palm) and the forearm is a large obtuse angle O1 and small supplementary angle A1. The inventors prefer an angle O1 of greater than or equal to 135 degrees and a corresponding supplementary angle A1 of equal to or less than 45 degrees. Possible ranges for the obtuse angle O1 may be, for example, 135-160 degrees, or especially about 135-155 degrees. Possible ranges for the acute angle A1 may be, for example, 45-20 degrees, or especially 45-25 degrees.
The Cannella sheath CAN-S and said prior art commercial product COMM, on the other hand, are adapted to hold the fingers, hand, and wrist in positions substantially similar to those portrayed by the bare-hand holding the board in
When inside the Canella sheath CAN-S, as shown by
The commercial product is likewise adapted so that the fingers, up to about the proximal inter-phalangeal joint (especially the distal phalanx and the middle phalanx), lie parallel to the front plane and the central plane of the board/target. In the commercial product COMM, as shown by
In summary, the surface that the user's fingers rest on, inside these prior devices, is parallel to the board, requiring the holder's fingers distal and middle phalanx to lie flat/parallel relative to the board's front and central planes, and forcing the heel of the holder's palm toward the board and further in toward the center of the target. These features of the prior art devices increases the likelihood of “jamming” the holder's wrist(s) as a result of a kick/strike.
Further, the Cannella sheath is described as “made of a tough, substantially nondeformable, abrasion and cutting resistant material, such as plastic or metal”. The prior art commercial product related to Cannella is advertised as being made of Lexan™ polycarbonate, which the inventors note is hard, rigid, and completely-inflexible, and tends to become brittle over time making it more susceptible to breaking/shattering when struck. Also, as shown to best advantage in
Inadequate Gripping Surface:
Padded gloves commonly available in martial arts circles may protect the holder's fingers to some extent, and may provide a cushioned surface should the breaker hit the glove. However, even conventionally-padded, prior art martial arts gloves decrease the holder's grip, resulting in the target acting “slippery” and being difficult to hang on to. Gloves with increased padding would only interfere further with the holder's grip on the board. The result of padded gloves, therefore, is typically a reduced grip on the target, increasing the likelihood of dropping or prematurely releasing the board/target during the attempt and resulting in a missed attempt on the break.
Therefore, there is still a need for an improved device for finger protection in martial arts, and embodiments of the invention meet this need. Certain embodiments of the invention provide correct ergonomic positioning that is very different from the positioning encouraged by prior art sheaths. Also, certain embodiments of the invention provide the holder with multiple options for hand and protector placement on the board, while also providing a sure grip. Also, certain embodiments comprise firm, but non-injuring and slightly-compressible, elements and surfaces that provide a surprisingly-effective balance of protecting/shielding the holder's hand/fingers and protecting the striker's foot and toes in the case of striking with the foot, or hands and fingers in the case of striking with the hand.
The invention comprises a device and/or method for protecting the fingers, hand, and/or wrist of a person holding a board or other target that a martial artist attempts to hit or kick with a hand or foot. In this description and in the claims, the term “striker” is used as a broad term that may include both a person kicking a board and a person hitting with the hand or any body part. Said protection may be protection from direct impact, for example, kicking of the fingers, and/or from the force/shock that is transmitted rearward to the hand and wrists of the holder of the board/target.
The device comprises an enclosure for receiving and holding multiple of a board/target holder's fingers in a generally curled or other inwardly-slanted position, as the user grips/grasps the board/target between the device and the user's palm. The structure of the device, and especially a slanted floor of the enclosure, result in said curled or inwardly-slanted position for the fingers, which places the rest of the hand, the wrist, and forearm in ergonomic and safe positions. In certain embodiments, the device is made entirely or substantially of material(s) in a particular hardness range that protects the user's fingers but that also tends to prevent injury to the person hitting/kicking the board/target.
In certain embodiments, an interior space inside the device is adapted to receive the user's finger(s) so that the holder(s) may use two of the devices, one on each hand, to hold a board/target generally in front of or to the side of the holder(s) for presentation to the striker. The board is typically held generally vertical, for example for side-kicks, or at other angles, such as 5-45 degrees from vertical for other types of front or round kicks, or generally parallel to the floor (flat or almost flat) for ax kicks. Typically, two holders are required or desired to hold a single board. Based on the orientation typically seen when the device is in use, structure behind the interior space rests on the board/target and structure in front of the interior space shield the fingers from direct impact. The rear portion of the device may comprise a rear wall, called in certain embodiments a “floor”, against which the fingers press, and one or more extension members/surfaces that extend out rearwardly from the floor wall to lie on a rear plane of the device. Said one or more extension members/surfaces is/are sized and shaped so that, when the extension members/surfaces is/are placed against the front surface of the board/target, the device is so oriented that the rear wall/floor is at an angle to the front surface of the board/target.
In certain embodiments, the device is adapted to be adjustable in position on the board/target, to give the user flexibility in grasping different portions of the board/target. Preferably, the device comprises no protrusions extending rearward of said rear plane, and thus, no protrusions extending rearward of the front surface of the board. Particularly, the device preferably comprises no plate or protrusion(s) that extend(s) along, around or behind the outer perimeter edge surface ES of the board/target, and no plate or protrusion(s) that contact the outer perimeter edge surface ES or the rear surface of the board/target. Such plate(s) or protrusion(s) could interfere or limit the placement of the device relative to the board, and, therefore, the preferred device (missing such plate(s) and protrusion(s)) may be moved inward relative to the outer perimeter edge.
Objects of certain embodiments of the invention, therefore, comprise implementing a protective device, for a martial arts' board/target holder's hands, that provides both impact and ergonomic benefits for the holder(s). Another object of certain embodiments is that employing such a device should not dramatically increase the likelihood of injury to the breaker compared to the breaker hitting/kicking a board/target that is held with bare hands and/or soft/flexible gloves.
Referring to the Figures, there are shown examples of bare hands holding a martial arts board, and also two prior art devices being used in holding a martial arts board. Also shown in the Figures are several, but not the only, embodiments of the invented, improved device for finger and/or hand and wrist protection in martial arts and methods of using the embodiment. Martial arts boards, including rebreakable boards, are well-known in the art.
Device 10 is representative of one, but not the only, embodiment of the invented device for finger protection in martial arts.
As shown to best advantage in
As shown to best advantage in
The floor 20 of the enclosure 14 connects, or is integrally attached to, the side wall portions 42, 44 of the front wall 18 and the distal portion 46 of the front wall. One may say the front wall 18 curves all the way to the floor 20 at two sides and at the distal end of the device, or one may say that the front wall 18 comprises sidewall portions 42, 44 and distal wall portion 46 that connect to the floor 20. The device's enclosure walls (18, 42, 44, 46, 20) are usually solid and continuous, but may optionally incorporate one or more openings for air ventilation. In
Extending rearward from the enclosure 14 is at least one rear portion of the device, which, in device 10, takes the form of multiple rearward-protruding extensions 50. These extensions 50 are generally transverse to the plane of the floor 20, and are generally parallel to the dividers 30 of the interior space. These extensions 50 each have a rear extremity that lies on the same plane, thus, defining a rear plane RP of the device (see
Thus, it may be said that, in certain embodiments, interior structure inside the device causes/urges the fingers to rest in said curled, inwardly-slanted, or other non-parallel position relative to the front plane and the central plane of the board/target. As shown in
It will be understand that one, or more commonly two, holders cooperate to hold a single board/target. The two holders will each grasp opposite edges of the board in their two hands. The device 10 allows the holder's hands to cup and grip the board at any point on or near the board's edge including corners, and at various angles relative to the board edge, as shown in
Semi-Rigidity:
Certain embodiments of the device are made of a semi-rigid material that resists collapse/crush from the initial impact force of the strike, including hits, blows, or kicks, yet is somewhat pliable so the breaker's hand/foot will encounter a slightly-yielding surface and be less susceptible to injury. The inventors believe that too-rigid materials may injure the striker and/or may become brittle over time making it more likely to fracture and cause injury to the kicker/striker and/or the holder, while too-flexible materials may allow injury of the holder.
The material employed preferably also incorporates a certain amount of “stickiness” to promote a measure of grip and skid resistance for both the holder's fingers/hand inside the device, as well as that portion of the device's surface that contacts the board. The material preferably also provides some level of elasticity to accommodate varying hand sizes. A variety of materials or mixes may create such properties, with the especially preferred material(s) exhibiting a durometer measurement from about 50 A to about 90 A on the Shore Hardness scale, and more preferably from 65 A to about 85 A. 85 A Shore Hardness is currently the especially-preferred hardness. These ranges of Shore Hardness Scale A, and particularly a hardness equal to, or about, 85 A Shore Hardness are particularly important in certain embodiments, to provide the desired balance between protection of the holder and protection of the kicker/striker. For example, 35 A Shore Hardness in many embodiments has been found by the inventors to be too flexible and soft, while 92 A Shore Hardness in many embodiments has been found by the inventors to be too rigid and hard. Examples of effective materials are thermoplastic elastomers, and especially thermoplastic vulcanizates (TPVs) such as Santoprene™, that are preferably in the 65-85 A Shore Hardness range. The overall outer shape of certain embodiments that use such semi-rigid material(s) as those described herein can be many different geometries, with the preferred embodiment using a rounded, domed, or “flattened dome”, such as device 10, to minimize tearing or cutting injuries to the breaker.
Certain embodiments benefit from providing a supplemental or different material, compared to the material(s) of the rest of the device, on the rearward extremities of the rear portion, for improving grip of the device on the front surface of the board. For example, the rearward extremities of the extensions 50, bars 150, pegs 250, walls 350, walls and blocks 450, and continuous-wall blocks 550, and the slanted protrusions from the right- and left-sidewalls (or the “right- and left-sidewall extremities”), and any other structure forming the “slanted rear extremity” may be formed of, or coated with, a softer and better-gripping material compared to the material forming the enclosures and the main portion(s) of said rear portion.
Angled Ergonomic Base:
Certain embodiments of the device use what may be called “an angled base” to support proper hand/wrist position when holding the target, as this is particularly important at the time of impact of the kicker's/striker's foot/hand against the board. This angled base holds the device so that the rear wall/floor of the finger compartment/interior space of the device is at an angle A to the board/target. Given the geometry of a human hand, the angle A of the rear wall/floor encourages the holder to place the heels of their hands nearer to the outer perimeter of the board/target as opposed to the inner or more central region of the board/target. As discussed above, the heel of the user's hand, when using certain embodiments of the invention, may actually be rearwardly-distanced from the rear surface of the board, due to the preferred “rotation” of the hand, as discussed above.
The angled base is provided by the rear portion of the device being specially-adapted to allow, and encourage, use of the device in the desired location and position on the board, as discussed above regarding
Said specially-adapted rear portion comprises structure that protrudes rearward relative-to the slanted floor of the device. The preferred structure has rearward extremity(ies) located and spaced so that said structure holds the floor at the desired slant relative to the board, without it being possible, or at least without it being likely, for the device to be used in a position where some of said structure is contacting the front surface of the board and some of said structure is contacting the outer perimeter edge surface of the board. A preferred example is the rearward extension system of device 10 comprising triangular rearwardly-protruding extensions 50 with rearward extremities/edges 56. These extensions 50 extend all or nearly all along the length of the floor 20, between the distal extremity 22 of the floor 20 (at or near closed end 32), and the opposite, proximal extremity 24 of the floor 20 (nearer the opening 34). The rearmost extremities/edge 56 of the triangular extensions 50, all along the length of the extensions 50, rest on the front surface/plane FP of the board, preventing the device from pivoting to diminish angle A, and thus preventing the floor from becoming parallel to the front surface/plane FP of the board. Extensions 50 are semi-rigid, as discussed earlier in this document, and the rearmost extremities/edges 56 are straight/linear. Therefore, the extensions 50 will not flex or compress to an extent that would allow the device to be “pivoted around the corner” to place portions of the extensions 50 both on the front surface and on the outer perimeter edge surface of the board. Thus, proper placement and use on the front surface of the board is required of at least encouraged by the structure of the device.
Said specially-adapted rear portion may comprise a rearward extension system of other forms/shapes, for resting on the front surface/plane FP of the board/target and place the rear wall/floor at the desired angle A. The rear portion may comprise other arrangements and numbers of plates, protrusions, or other supporting structure, for example, a single or a plurality of solid or hollow structures having a rearward extremity(ies) that contact the board/target sufficiently to stabilize the device against the front surface of the board/target. For example, instead of or in addition to the multiple parallel triangular walls 50, pyramids, pillars, bars, blocks, pegs, posts, straight walls, curved walls, other such geometric shapes such as honeycombed cells, and any combination of these shapes/structures, including hollow, partially hollow, and solid, may be used. The extensions may be fixed to or integral with the floor of the device, at multiple locations between, or extending substantially the entire distance between, the proximal extremity and the distal extremity of the floor. Some of the extensions, and/or some portions of the extension(s), are located on each of the right and left sides of the longitudinal central axis LA (“length axis”) of the floor, and on each of the distal and proximal sides of the transverse central axis WA (“width axis”) of the floor. It will be understood that “portions” in this context result from extensions extending across the axis LA, and/or the axis WA. Hence, it may be said that an extension has a portion, or extensions have portions, on both right and left sides of the axis LA, and/or both the proximal and distal sides of the axis WA. The extensions preferably extend, or are arranged, generally symmetrically on each side of the longitudinal central axis LA of the floor and on each side of the transverse central axis WA of the floor, for increasing contact surface area between the device and the board, increasing stability of the device on the board, and benefitting load transfer. The longitudinal central axis LA is half way between the right and left sides of the floor 20, and the transverse central axis WA is half way between the distal extremity 22 and the proximal extremity 24 of the floor. See
The rearward extremities of structure/protrusions forming the angled ergonomic base may comprise extensions of the wall(s) that form the enclosure 14. For example, as noted above, the rear portion of device 10 comprises far-right and far-left extensions 50 that extend from the sidewalls 42, 44, in addition to the five more-centrally-located extensions 50, as shown in
Extension 550 is an example of a hollow block/structure protruding from the floor and having a slanted continuous rear wall, wherein the slant relative to the floor provides the desired angle A. Alternatively, extension/block 550 may be solid rather than hollow. Thus, it will be understood that certain embodiments have a continuous, rearward extremity wall surface extending all or substantially all along the length of the floor and the width of the floor, and such an extension/block may be hollow, partially hollow, or solid. Compared to these “continuous-rearward-extremity-wall” embodiments, however, embodiments that include multiple, spaced-apart protrusions (such as triangular walls, pyramids, pillars, bars, blocks, pegs, posts, straight walls, curved walls, other such geometric shapes such as honeycombed cells, etc.) are preferred because they may be beneficial for polymer molding methods of manufacture of the device.
It may be noted that the preferred rear portion/extension system of the invention is different in structure and function compared to the single flange FL, or the flange FL combined with the spikes 14, of the Cannella devices of
Load Transference:
The interior space of the device is preferably divided into multiple sections/portions. The device may use single or multiple dividers equally or unequally spaced across the compartment. Those dividers may be parallel with the device's sidewalls, or may employ a non-parallel orientation such as in a radiating fan shape. In the preferred configuration, the finger compartment is divided into four sections, with three dividers providing load support to transfer the breaker's force from the device's top/outer plate (the frontmost extremity of the front wall) to the rear wall/floor and then to the rear portion/extensions of the device that are in contact with the board. Such dividers also provide a gripping surface for the holder's fingers. The divider(s) may be curved at their proximal edges 31, as in device 10, to minimize the chance of pinching or scissoring the holder's fingers against the board surface.
It may be noted from the drawings, that the center divider 30 of device 10 is coplanar with the central extension 50 and that the sidewalls (sidewall portions 42, 44) are coplanar with the outermost extensions 50. These features may enhance load transference in certain embodiments. It may also be noted that the other dividers, that is, the dividers directly adjacent to center divider are parallel but not coplanar with any extensions. Thus, it may be said that some of the dividers 30 are co-planar with the extensions 50 while some are not. Alternatively, the dividers may be other shapes and arrangements in certain embodiments. Each divider may be solid, planar, and continuous, such as shown in device 10, to maximize support and load transference, or alternatively may employ one or more holes, openings, ribs or reinforcements, for appearance and/or to enhance the divider's role in transferring the force through the device to the board and/or otherwise protecting the user's hand. It may also be notes that the extensions 50 may be other shapes than those drawn, for example, arches.
The device's floor 20 may be either smooth or feature raised protrusions or other texture to enhance grip and inhibit slip. As illustrated in
It should be noted that the terms “front” and “rear” are for convenience in describing various aspects of the protector device and are not necessarily intended to limit the use of the protector device to particular orientations.

In certain embodiments, the front wall, the entire enclosure, or the entire protective device may be made from material characterized by having a Shore Hardness in the range of about 65 A to 90 A, for example, or more preferably about 85 A. The front wall may have a planar main portion that is at an angle to the rear wall. In certain embodiments, the device comprises no structure that extends rearward from said rear plane, to enhance the options for placement of the device on the board.
Certain embodiments may be described as a finger protector for holding a martial arts board, the protector being adapted for receiving distal portions of fingers of a user, and the protector comprising a front wall for receiving an impact from a striker of the board, a rear wall for being pressed-on by the fingers or fingertips of said fingers, and a rear portion for resting on the martial arts board, wherein the rear wall is at an angle, to the rearmost plane of the rear portion and also to the front surface of the board, in the range of 5-45 degrees, to cause the user's hand to rotate forward relative to the board when grasping the board between the device and the user's palm, for placing the user's hand and wrist in an improved ergonomic position for increased safety.
